APAR Error Description / Circumvention

-------------------------------------------------A subset main store dump copy is progressing very slowly.

CORRECTION FOR APAR 'MA45446' :-------------------------------During the subset dump analysis many large seize/lock segmentswere found and they are copying very slowly. The LIC was changedto recognize the large segments and switch to a FULL main storedump copy. Switching to a full dump causes the segments to beaccessed differently and the copy performance is increased.

If a subset main store is copying slowly. The copy can beterminated with a F15 (twice). The user can then use the Workwith copy options and change the option Subset if possible to a2 (2=No, if enough room for full copy). Then restart the dumpcopy.Then after the copy, change the option Subset if possible backto a 1 for a subset copy.
